We propose a generalized T-matrix definition that facilitates the conversion between the S-parameter and T-parameter for multiport networks based on the well understood and mathematically simple two-port relations. This approach generalizes all multiport networks into two cases: balanced and unbalanced. Balanced networks have the same number of en- trance and exit ports and are symmetric to the two-port network. Unbalanced networks generate a nonsquare T-matrix and do not have the same number of entrance and exit ports. Through careful selection of the T-matrix, this method extends two-port symmetry to multiport networks and provides an engineering implementable relationship between the S-parameter and T-parameter for multiport networks. This symmetry extension allows a practical means to cascade and deembed such networks. [ABSTRACT FROM AUTHOR]
